I still don't want to have to construct a table with around, say, 60 combinations of which only around, say, 20 are distinct.
I'd also take the approach to normalize the 60 posibilities, i.e. coerce them into unique keys in the dispatchtable, with e.g. 
$key  = 'default';
$case =~ s/$reg2// && ($key = 'a');
$case =~ s/$reg1// and do { whatever(); $key = 'b' };
...

and finally dispatch via a table 
$dispatch{$key}->(@args);

[download]
Can anyone see any possible drawbacks to this approach?

Not yet, since neither context nor implementation are visible...
